"JNO. G. WVEBB, OF WILLIAMSBURG, NEW YORK.

ARGAND GAS-BURNER.

Specification of Letters Patent No. 8,437, dated October 14, 1851.

To all whom it may concern:

Be it known that I, JOHN G. IVEBB, of IVilliamsburg, Kings county, Stateof New York, lamp manufacturer, have invented, made, and applied to usecertain new and useful improvements in Argand burners, for

- the ordinary Carbureted Hydrogen or other similar gas by theapplication of a cone for the purpose of regulating the outer draft anddeflecting the flame, for which I seek Letters Patent of the UnitedStates; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the annexed drawing,making part of this specification, wherein Figure l, is a plan with thebutton removed and Fig. 2, is a section of my improved burner.

The like marks of reference apply to the same parts in both figures.

In these a, is a pipe conveying the proper supply of gas and on the endof this tube is a plate 6, either preforated with holes or made witharms that carry a ring flanch which supports the chimney or glass 0, andthe short pipe 1, on the end of the tube a, receives a hollow yoke (Z,that carries the perforated Argand burner e, and supplies gas to thesame and from the center of the yoke (Z, is the stem of a button f.These parts so far are made nearly the same as in my patent of 7 Aug.1849 for a self generating Argand gas burner but I use this for theburning of gas that has been generated by other means and conveyed inpipes or tubes to the burner and I also place a cone 9, around the.burner 6, extending down to and supported by, or made with the plate 6.This cone is contracted till it comes near the lower edge of the burnerand the upper part is parallel or may be slightly flaring out so as tobe nearest the bottom of the burner, e. In the plate Z), are holes 2, or

an annular opening around through the plate between the cone 9, andchimney c. The burner 6, may be a tube with holes to pass out the gaswhich produces the same effect as the one shown, or a narrow slit may becut around the burner to pass the gas out instead of the holes, or theburner may be made as a double cylinder of any required depth with theopenings for the gas on the top as before.

Having thus described the construction,

the operation and effect is as follows: The gas passing from the pipe(6, through the yoke d, enters the burner c, and issues through theholes in the top of the same where it is to be lighted. The draft nowpassing up through the cone 9, a portion enters inside the burner e, andanother portion passes outside the burner 6, between that and the cone9, which it will be seen is but a narrow annular opening from the bottomof the burner to the top this supplies the proper amount of air at thebase of the flame for the purpose of brightening it, but is notsufficient to overcome or prevent the inner draft as it passes up beingdeflected by the button f, and spreading the flame in a largesemi-globular form, and the further supply of air outside the cone bythe holes 2, completes the combustion on the outside of the flame, andprevents smoke.

It will be seen that the main improvement is the introduction of thecone to an ordinary Argand burner for although Argand burners have beenused for gas, the light is not steady as will be evinced by the removalof the cone, the flame immediately flickering and becoming unsteady, thecone in mine concentrating the draft,-and by being rather close to theburner 0, also brightens the light very importantly, by supplying theproper amount to the outside of the flame at its base.

I am aware that a burner has been pat entecl covering a long expansivechamber to contain the gas to be burned, but in my burner the ordinaryArgand burner is used, which is public property; and the patent beforereferred to covers a bell shaped mouth formed by the lower end of thegas chamber or burner, .but in my improvement no such bell shaped mouthis used, and I use a cone which I am not aware has ever been used wit-hany other Argand hydrogen gas burner and although a cone has been usedwith a circular wick burner it will be seen that the Argand carbonatedhydrogen gas burner is entirely different both in the material burnedand in the construction of the parts.

Therefore I do not mean to limit myself to the precise shape of the yokeor to the proportions or size. of the parts as these must be variedaccording to the amount of draft required for different qualities ofhydrogen gas, neither do I mean to limit my self to the shape of theburner as long as the Argand principle of the inner and outer draft ismaintained, and though I have described the cone as contracted at thebase of the burner and slightly larger near the flame as the bestarrangement I have found in practice yet some qualities of carburetedhydrogen gas or a difference of pressure in the supply may require thecone to be parallel to the top or contracted at the top. I therefore donot limit myself to the exact form shown at the top of the cone becausethe variations thus stated are merely practical and contingent While themain features of the application described remain substantially the sameas set forth.

I therefore claim- The construction and use of an Argand burner andbutton With a cone to regulate a supply of air to the base of the flamein combination With an outside draft between the cone and a suitableglass chimney to complete the combustion and turn the flame over thebutton such parts being applied to burning carbureted hydrogen orsimilar gas, substantially as described and shown.
